AUTOMATIC swrrcn. a

To all whom it may concern:

Be it known that I, FRANK FUNKE, a citi zen of the United States, residing at Independence, in the county of Jackson and State of Missouri, have invented new and useful.Improvements in Automatic Switches,

of which the following is a specification. I

This invention relates to automatic circuitthe generator circuit and whereby upon any rupture of the generator circuit or any accident to the generator, the battery circuit will be automatically completed.

A further object of the invention is the provision of means included, in the switch -'circuit for indicating the condition of the battery circuit and the generator circuit.

Further objects of the invention will appear as the following specific description is read-in connection with the accompanying drawing which forms a part of this application, and in which: 7

Figure 1 is a top plan view of the preferred form of switch, and Fig. 2 is a diagrammatic view of the circuit employed.

Referring more particularly to the draw ing 1 represents a base upon which is mounted a suitable switch 2 provided with av terminal binding post 3 which is connected in series with the battery B. The opposite side of the switch is connected by means of a conductor 4 to one side of asignal lamp L whose opposite side is connected by means ofa conductor. 5 to a contact 6 which is normally engaged by a switch lever 7 operated by a spiral spring 8 and pivoted upon the vertical standard 9 carried by the base. The'switch lever is connected by a conductor 1,0 to the opposite side of the battery 13.

This switch lever is constructed of magnetic material-and is provided with a non-mag- W =netic stud 11 in its end so as to prevent sticking to the core 12 of the magnet 12?. The magnet 13 is included in the c rcu t with the magneto and an independent circuit 14 is connected to the magneto termlnals Specification of Letters latent.

and, consisting of a part of the battery circuit, includes aspa'rk gap 15 and a spark coil 16. The magnet 13 is adapted to act upon the switch lever 7 and withdraw from the contact 6 to break the battery circuit.

While I have not shown the connection of the battery and generator circuits with the timer, it will be clearly understood by those versed in the art that the timer is connected in the circuit shown, in the usual manner. When the switch 2 is thrown to complete the battery circuit, the lamp L" is lighted and remains lighted until the engine attains a speed suflicient to cause the magneto or generator to energize the magnet 13 at which time the switch lever 7 is withdrawn from the contact 6, thus breaking the battery circuit and putting out the lamp. This indicates that the generator is operating to supply the spark plug with a sufliciently hot spark to ignite the fuel. If the generator should become accidentally broken or the generator circuit ruptured, the magnet will fail to operate and the switch lever 7 released and the battery circuit thus automatically completed. -I have shown a sparking arrangement 15 consisting of two separate points and a coil 16 included in the generator and battery circuits, but any form of sparkingarrangement may be controlled by this system so that when the engine has attained sufficient speed to give the magnet a proper amount 9f current the battery circuit will be broken and when the generator is stopped or broken, themagnet will be reenergized and the battery circuit completed to the sparking arrangement.
